' .The presentinvention pertains in general 149,549 filed November 20,1926, the subject to covers for culinary vessels and moreparticularly toself-basting forroasting pans and the like of the general type disclosedin my Patent No. 1,598,222, dated August 31,1926,

and in my co-pending application, Serial No.

' matter of the presentapplication being divithorough browning of theroast and thGICOVGI V '20 ends may be brought to'a size to permit thesional'of said application.

In accordance with the general features of my present invention Iprovide a j cover equipped with means for promoting the condensation ofthe vaporized juices of the roast, and for directingand distributingthejuices evenly over the roast. In addition the cover of the presentinvention allows the steam to escape'and thereby produces a solution ofhighly condensated grease which provides a of the present invention is aself-basting cover to such an extent that the attention of a person isnot required. V v 7 The cover of the present invention is a relativelythick walled cover and I find that by tapering the apertures through therelatively thick wall ofthe coverthe inner restricted passage of steambut'restrict the passage of the'more viscousfats and at the same timethe taper of the apertures forms the condensation pockets within thethickness of the.

objects; and "advantages; of i the Y 7 present invention 'willmore fully,appear it from the following detailed description taken in connectionwith the accompanying drawing, in which i V Fig. 1 isa cross sectionalview through a cover embodying the present invention; .and

Fig. 2 is a similar view through another trated therein is designatedgenerally by the reference character 10 and is illustrated asarelatively thick walled cover. Where Irefer to relatively thick'walledcovers herein, I intendthereby. to distinguish from the relatively thinwalled covers well known in the art and commonly formedof sheet metalerally cast or made up in the form of castings but it is to ,beunderstood that this'may be tion of-the tapered basting apertures withtheflthick walled cover. a

' It will be notedthat the cover 10 is illustrated as equipped with aplurality of these tapered apertures 12 which are preferably so spacedfrom each other and distributed over the cover that a uniform bastingaction will ;be ,produced thereby. In Fig. 1 the apertures 12 convergedownwardly and are confined from end to end within the thickness of thewall of thecover, being disposed within said wall thickness and formingcondensation'pockets wholly within said cover wall thickness.

i The restrictedinner ends 13 of the tapered apertures 12 openthrough-and are disposed at the inner surface of the cover wall and theenlarged outer ends 14 0f said aperture open through and are disposedatthe outer surface of said cover wall. In this mannerneither the innernor outer surfaces ofthe wall of the These relatively thickwalled'covers are gen- 2 varied within the scope of the presentinvention, the gist of which resides in the combina= cover need beprovided with depressions or projections with the result that the outerand under surfaces of the coverare relatively smooth and cleaning isfacilitated and possibility of scratching the fingers avoided.

The tapered apertures 12'serve as a means for permitting the steam topass through the cover. Also, these apertures form air vents for theinterior of the vessel and serve to pre vent the boiling over of thecontents within the roaster or other pan or vessel with which the coveris employed. Still further the apertures 12 promote condensation of theva porized juices of the meats or other food being roastedland thethickness of the wall of the cover in combination with the taper of theapertures forms condensation pockets without additional pocket formingoperations, as heretofore. These condensation pockets collect-anddistribute the. condensates uniformly over the roast or other food inthe vessel with which the cover is used. The thicker the cover wall,"obviously the less 'thetaper required to produce condensation pockets ofequal size.

The condensation pockets are formed whol- 1y within the thickness of thecover wall, the

size of these condensation pockets beingdependent solely uponthe taperof the apertures a'nd'the thickness of the wall ofthe cover and thesizeof'the restricted inner end of each aperturebeing independent of thesize of the condensation pocket. The tapering of the apertures 12 alsoincreases the condensing surfaces about said apertures;

- The cover 10 shown in Fig. l is raised at 16 and the top 18, throughwhich the tapered apertures 12 are provided, is shown as being flat, butit is to be understood that this cover may be of semi-spherical or"dome-shaped form or of any other suitable or preferred shape.- Fastenedto the central portion of the apertured top wall 18 of the cover 10 is aknob-like handle 20 which may be securedto the'cover as by means of ascrew 21 with a washer 22' interposed between the head of the screw andthe inner surface ofthe cover. The

cover 10 is also shown as having an annular rim 25 and a downwardlyextending annular flange 26. The rim 25 is adapted to rest upon the topof the roasting vessel or the'like the depending flange 26 is adapted tolitv down internally therein. It is to be understood, of course,'thatthe tapered apertures 12 may be arranged in staggered rin g-likeformation or otherwise over the entire surface of the. cover to obtainthe desired uniform action.

In Fig. 2 I have illustrated another form of the present invention. Inthis case the cover is designated generally by the reference character28 and again is a relatively thick, walled cover preferably in the formof a casting. The cover 28'is shown as of semispherical or dome-shapedform'and has an annular-rim 29 and a depending annular flange 30 adaptedfor cooperation with the roasting vessel. as explained in. connectionwith the embodiment of Fig. 1. The cover 28 is provided with ahandle 32which may be fastened thereto similar to the attachment of the handle intheprevious embodiment or otherwise, as desired.

' Formed integral with the inner or under mitting the steam to passthrough the cover and form air vents for the interior of the vesselaswell as serving to prevent the boiling over of the contents within thevessel. Furthermore, as before, the apertures promote condensation ofthe vaporized'juices of the meat or other food being roasted and collectand distribute the condensateuniformly over the roast or the food.

The taper of the apertures 35 is shown as being less pronounced than thetaper of the apertures 12 because of the greater thickness providedalong the apertures by the depending annular ribs 34 of the embodimentof Fig. 2 than along the apertures in the embodiment of Fig. 1. In theembodiment of Fig. 2, as in the, embodiment of Fig. 1", the taper of theapertures 35 forms the condensation pockets within the thickness of thecover, portion surrounding said apertures and, as before, the enlargedupper ends of the apertures open upwardly to form condensation pocketsin the wall of the cover, the size'of these condensation pockets beingdependent solely upon the taper and depth of said apertures andtheopening of the inner ends of said apertures through thecover beingindependent of the size of the condensation pockets,

I do not intend to be limited to the precise details shown or described.

I claim:

1. An article of manufacture comprising'a relatively thick walled coverfor cooking utensils, means comprising a plurality of apertures formedin the cover wall and opening through said wall for permitting theescape of steam outwardly through the cover and the dripping back ofcondensation in wardly through the cover. said apertures being enlargedoutwardly within the thicknessof the cover wall and having enlarged endsat the outer side ofthe thickness of the cover wall and reduced ends atthe inner side of the thickness of said wall, the thickness of the coverwall being sufiicient and the outward enlargement of said apertures suchas to form condensation collecting pockets wholly within the thicknessofthe wall of the cover and solely by the outward en largement of saidapertures within the thickness of said wall and without bending the wallof the cover in addition to providing steam escape and condensation dripback apertures in order to form condensation collecting pockets adjacentsaid apertures.

2.- An article of manufacture comprising a casting forming a relativelythick walled cover for cooking utensils, means comprising a plurality ofapertures formed in the cover wall and opening through said wall for permitting the escape of steam outwardly through the cover and the drippingback of condensation inwardly through the cover,
